Dear team

In our Client Production Environment QV11 SR13 during Opening of Dashboard on access point we are getting ""SESSION LOST""

message and unable to open the qvw file.

RAM IS=768 GB .AND SIZE OF DAHSBOARD MODEL =10GB.

Below optioned we trried but not able to resolve the issue:

1) We have increased <QVSTIMEOUT> FROM 60 T0 3600 but still getting Session lost.

2) REATRTED THE SERVICES AND TRIED AGAIN BUT STILL GETTING ""SESSSION LOST""

3) REMOVE LAST DOCUMENT STATE IS ALOS TRIED BUT DID NOT SOLVE THE ISSUE.

4) FROM QMC WE TRIED to increase session time also but did not get the ouput.

Can you please advise what could be the cause of ""session LOST"" and how to resolve it.?
